You Always Learn Something

The weekend of June 25 – 26, 2016 was Field Day, an opportunity to get on the air, test out some gear and generally have a good time operating. While many Amateurs were busy with Field Day, a small group of PWCARES members were participating in Operation United Resolve, a national communications exercise. The scenario was:

A series of catastrophic events across the United States has occurred. California has been hit by a massive earthquake causing extensive damage as well releasing a tsunami which has hit Alaska causing damage there, the central states experienced a derecho wind storm that caused extensive damage to the power distribution system, and at the same time a F5 hurricane travelled up the eastern seacoast flooding coastal areas. Additionally with these natural occurrences, various areas of the country are experiencing sporadic power outages of varying durations and fluctuations of unknown origin.

Many Governors state that their emergency management resources are overstretched and are asking neighboring states for assistance. As part of the recovery effort, SDFs across the US are mobilizing to assist their state Air/Army National Guards as they are called to active duty. Establishing reliable communications is a part of that effort and is the first step in determining who can communicate and what their local operating status is.

While a bit unrealistic, any one of these events could lead to a national call up of resources and strain the system.

The bad news is that the exercise never really seemed to get off the ground, at least as far as we could tell from our listening post at PWCARES headquarters.

The good news is that, even from this small, non-exercise, things were learned.

  • HF is hard : Perhaps it is better to say, if you do not do it a lot, HF can be challenging. The first thing we learned is that gear left in storage can, and does go bad. Or at least it seems like it does. Brian, WC4J, brought his IC–756ProII out to use and for a few, tense moments, we thought we were not going to be able to see it because the backlight did not seem to work. It did eventually, but there is a long track record of the backlights failing on that model.
  • Keep your gear together : It was a good thing Brian brought his rig, because David, KG4GIY could not find the tuner for his IC–706MKIIG (it did eventually turn up late on Saturday but only after a small excavation of half the house). This is not just for HF and tuners, but all those necessary cables, jumpers, and sources of power.
  • The higher the better : Putting up antennas is an art. Especially when you do not have all the height you might want. As we discovered hanging David’s G5RV Jr, even though the oak trees were high, getting the cables over the right branches to pull the antenna up was as much of a challenge as where to tie off the legs. Still, it was high enough that we could talk to others, and hear as well.
  • Sunspots matter : When all is said and done, if the sun is in a low activity pattern, the bands are not going to behave. As we have learned, we are in a real trough of solar activity and things are likely to continue this way for a while.

Despite only hearing two calls on the frequency we were instructed to monitor, and neither one of them requiring us to call back, we had a good exercise and everyone learned something useful.

My thanks to Brian, WC4J; Mary, KK4GOW; Derek, KV4SH; and Jack for coming out and exercising, and Jeff, WB6UIE; who was remote but proved we were getting a signal out.

Operational Parameters

We will be testing the K3FBI repeater at 147.345+ PL 167.9, the Woodbridge machine at 147.240+ PL 107.2, and simplex at 147.525, the normal ARES operational frequency. Please ensure each of these frequencies and their PL tones are in your radio to make net changes efficient.

Each operator will be asked to take up station at one of the parking lots or crossroads as indicated on the check sheet which will be provided on Saturday morning along with a copy of the map. We will then systematically check that we can hear each other at each location around the park in each mode. You will likely want to have a pen and paper with you.

Results

Thanks to those who came out and to the K3FBI repeater association and Woodbridge Wireless. The weather was overcast, the trees were mostly bare. Operators set up at the Start/Stop location, parking lots C through I, Burma Road/Scenic Drive and Oak Ridge/Scenic Drive.

Start/Stop, Lot C, and Oak Ridge utilized 1/2 wave or greater antennas, most on tripods. The rest used some form of vehicle mounted antenna. Radios were primarily mobile radios running at 50 watts. In one case, while running Simplex, Burma Road utilized an HT at 8 watts, with a small mag-mount.

The test was to evaluate the performance of two repeaters (K3FBI, WWI) and simplex for use in the passing of messages for the Marine Corps Marathon Crossroads 17.75 race, to be held April 2, 2016 in the Forest. We know that the Forest presents unique challenges for radio communications and we needed to ensure that options were available come the event day.

General Results

In all, both machines and simplex worked acceptably, with varying results of good, while simplex seemed to work the best over all. In general, the K3FBI machine performed better than the WWI machine, as expected.

Specific Results

Despite being pointed out prior to the event, we had some issues with PL tones not being pre-programmed. This resulted in negative connections. There is also one indication of location deafness which may be a machine issue, a location issue, or both between Lot I and the K3FBI machine. We also experienced difficulties communicating between Lot I and Lot G, despite there being no issues communicating between Lot I and Lot H and Lot G and Lot H. Further investigation into the geography, topology, and geology between these locations will need to be undertaken.

Start/Stop

Start/Stop was running a mobile with a full wave antenna on a tripod. In all situations, the signal between Start/Stop and other locations was solid with this set up on all machines and simplex.

Lot C

Lot C was also running a full wave antenna on a short tripod with a mobile. There were some poor signal reports on the K3FBI machine and the WWI machine. This is likely the result of topology. Simplex resulted in a good, strong signal.

Oak Ridge

Oak Ridge was also using a full wave antenna and mobile on a short tripod. Results were mixed. Reports against K3FBI were mostly strong, while against WWI, they were weak to no response, likely because of PL. Simplex was also strong.

K3FBI Grid

Note (R) meant the signal was heard on the reverse, not the repeater. In one case, due to PL, in the other case, location and possibly an issues with the repeater.
